Detailed Review
Green Mountain describes its sites by power source and climate: hydropower, cold-climate free cooling and heat reuse. Its Norwegian sites are SVG-Rennesoy near Stavanger, TEL-Rjukan in Telemark, OSL-Enebakk near Oslo, OSL-Hamar and the newer SVG-Undheim campus.
Abroad it runs LON-East in London, bought through the acquisition of an existing company, and is developing FRA-Mainz in the Frankfurt region together with the German power company KMW. The brand is a registered trademark owned by Green Mountain AS.
Three ways to rent space
The colocation page splits the offer into rack by rack (shared containment, from one 42U rack), private cages for roughly 4 to 20 racks, and data rooms from 50 square metres aimed at 20 racks or more. Rack-by-rack service includes two PDUs, cable trays, blanking panels and hot aisle containment.
Power is invoiced by usage and basic services such as security and waste handling are included, which makes the bill easier to model than a flat per-kW commitment.
Why the location matters
Norway gives low-temperature cooling and hydropower, which is the basis of the efficiency claims on the site. A public CO2 calculator lets a prospective customer enter a workload and see the estimated difference.
Submarine fibre cables provide connectivity to Europe and the US, so latency to central Europe is a question to test rather than assume.
AI and HPC halls
Green Mountain advertises high-density, liquid-cooled halls and says it has signed a contract with a neocloud operator at LON-East in September 2026. Services page entries list build-to-suit for multi-megawatt requirements, with colocation deployments targeted at 90 to 120 days.
Limitations to Consider
Most capacity is in Norway, which is outside the EU (but inside the EEA), and latency to Frankfurt or Paris has to be measured. The German site is still under construction. There is no price list, and the owners of Green Mountain AS are not named on the pages read. For a Dutch, German or Swiss footprint, look at NorthC instead.
Who Should Use Green Mountain
Teams with high-density or power-intensive racks that can accept a Nordic location, and cloud or AI operators that want hydropower on the invoice.
